South Korean officials said the latest accident took place at dawn during a military exercise when a star shell struck through two walls of an old woman's house.

When astronomers talk about the "habitable zone," they mean the shell around a star where the temperatures are right for liquid water.

当天文学家谈及“可居住区”时，他们指的是恒星以外温度适于液态水存在的空间层。

Infrared images from the Spitzer Space Telescope (yellow, red, and green) expose a surrounding shell of dust and gas that's being lit up as the material streams through a nearby star cluster.

由斯皮策太空望远镜拍摄到的红外照片(黄色、红色、绿色部分)正好是这颗气体恒星穿过附近的星团时，所显露出的尘埃及被点燃气团的外部结构。

How much of a premium are you willing to shell out for something as cool as a Star Trek Enterprise Pizza Cutter?

你愿意为像《星际迷航》的企业号比萨刀一样酷的玩意付多少钱？

当核燃烧向外进行到核心周边壳层的新物质时，恒星会膨胀成所谓的红巨星。

When sent to eliminate the crew of the Far Orbit, he was also tasked with securing the spacelanes from Vedij's plundering of the Ringali Shell, home to half a dozen highly-populated star systems.

当被派遣去处死“远轨”号上的乘员时，他同时还肩负有保证从维希夫所劫掠的林加利表层一直到数个多人口星系之间的航路安全的职责。

The authors suggest two possible explanations. One is the explosion of a star of over 90 solar masses, which will often expel a hydrogen-poor shell shortly before dying.

作者给出了两种可能的解释：一是，一个90倍于太阳质量的星体爆炸，会在其自身毁灭前释放出贫氢壳。

Gravity from the larger White Dwarf slowly pulls helium from the surface of its neighbor, and the siphoned gas builds up into a shell around the star.

从较大的白矮星重力缓缓进站从邻国表面氦，而抽走瓦斯积聚成空壳了围绕恒星。

When the hydrogen in the shell, too, is exhausted, the star takes to fusing helium there.

当壳层中的氢也燃烧殆尽，恒星便开始融合氦。
